Does anyone think a crypto sports trading project can succeed?
I suppose you wanted to say a Crypto sports
betting website? I don't see a reason for a project to fail as long as the business plan is reasonable. I am not into betting so can't give any advice but there is Sportbet.io, I participated in their advertising campaign in their early days and I see they are still here. So I guess it's working well for them...
FYI, they are the worst thing happened to bitcoin sports-betting scene. They are a well-planned scam running multiple scam gambling projects. Anyway, OP there is a huge scope for sports betting projects as long as you have the right talent to market it. It's not just limited to good UI or fair anymore, people are more concerned with support, speed, and anonymity. Observer the existing sites to figure out what they lack, you can take those negatives to plan your project accordingly.
I wouldn't consider this sports betting, but more as investing. If your team loses, you won't lose everything; the team's value will just decrease. Have you tried many crypto betting sites?
